Trace element accumulation in anadromous sea lamprey spawners [PDF]
Ecology of Freshwater Fish, 2013 AbstractThe sea lamprey, Petromyzon marinus, is an anadromous cyclostome that occurs in the main Western Europe river basins draining to the Atlantic Ocean and considered a gastronomic delicacy in Portugal, Spain and France.
